The 80 selected annotated games offer excellent material for study: top players such as Carlsen (2 annotated games), Caruana (1), Anand (4), Aronian (2), Esipenko (1), Giri (6), Gukesh (1), Karjakin (2), Keymer (1), Kramnik (3), Navara (3), Radjabov (1), Vidit (2), Vitiugov (1), Wojtaszek (4) have analysed their games and in addition there are comments from Queen’s Indian experts like Krasenkow (90), Gershon (76), Atalik (45), Marin (35) and Roiz (34). There is a total of 9687 games where the average rating is at least 2600, apart from games with annotations by Queen’s Indian experts Sergei Zhigalko and Sergei Tiviakov (with Black), Loek van Wely (White) and Anatoly Karpov (both colours).
A double click on the database loads the games overview. A further double click loads the relevant game. The tab Players allows you to sort the games according to frequency (using the tab Total). That leaves Anatoly Karpov at the top with 406 games, but he has almost the same number of Whites as Blacks. It is worth studying the games of Sergei Zhigalko and Sergei Tiviakov who played all of his 343 or 266 games with the black pieces. It is also interesting to click on Title; (for that a current Player Encyclopaedia needs to be installed); you see that almost all the world champions had or still have the Queen’s Indian in their repertoire.
The games can be played through or further investigated with an engine or a Powerbook.
